As stated above, e-mail cannot be used to perform procedural acts. If, e.g. shortly before oral proceedings, the applicant would like to submit new requests and/or amended documents, this should be done by fax, since only this ensures that the filed documents are given a valid date of receipt and form part of the file. Experience has shown that faxes are normally visible in the electronic file on the same day. As stated above, an informal copy, in addition to the fax, can be sent to the examiner for the convenience of the Division if this is felt necessary due to the short time frame.
